APPENDIX—HYALINIA NITIDULA. 467 
Geographical Distribution.—In Scotland, Dr. Frew has established 
its presence in the Island of Iona, Mid Ebudes: while Westerness has 
also become included among its known habitats by the aid of the govern- 
ment fund, granted to assist us in increasing our knowledge of the 
northern range of our mollusca. 
In Wales, Mr. J. Williams Vaughan has established its occurrence at 
Velinnewydd, Radnorshire. 
In Ireland, Mr. P. H. Grierson has added to its known distribution by 
its discovery in Longford county. 
The known continental range has been increased by its discovery in 
North Holland by Mr. F. H. Sikes ; at Sensburg in Kast Prussia by Mr. 
H. Sell; and in Denmark is said by Steenberg to be found everywhere in 
the woods. 
In France, Mr. F. H. Sikes has added Eure, Eure-et-Loire, and Indre-et- 
Loire to the list of departments where this species is known to occur ; and 
M. Granger has also recorded the Landes, Basses Pyrénées, Gironde, and 
Charente Inférieure. 
In Austro-Hungary, Dr. Reinhardt records it from the Sudeten in 
Moravia; and F. J. Schmidt from Carniola.

Hyalinia pura (Alder). 
Nomenclature.—Comm. Caziot (Moll. Monaco and Alpes Mar.; 1910, 
p. 42) relying upon Dr. Westerlund that Hyalinia nitidosa comprises the 
A. pura Alder and the H. hammonis of Strém, has separated the two 
forms, and superseded the name of pura by that of nitidosa for the 
smooth form, and for the radiately sculptured form adopted the name 
hammonis of Stréim in preference to //. radiutula Alder.
